DOMESTIC PRIORITY

This application is a continuation of U.S. patent application Ser. No. 15/689,038, filed Aug. 29, 2017, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

The present invention relates to remote viewing of a user interface, and more specifically, to providing instruction to a host computer system during remote viewing of its user interface.

Screen sharing or desktop sharing enable remote access and control of a host computer system by a remote computer system via a network. Remote desktop software may be provided as an application, hosted service, or as part of an operating system to allow a desktop environment to the run remotely whilst being displayed on a separate client device.

This may be used in a number of different scenarios, one of which is to assist the user of the host computer system with operation of one or more applications running on the host computer system.

This may be used during a web meeting as a means of enabling two or more users to view and act on a screen. This is useful in providing instructions on how to interact with an application being displayed. In one example, a screen with an application may be shared with a wizard page and the other user in the web conference may be providing assistance for driving the application. This occurs in scenarios such as support where one user is sharing a screen that they are having an issue running and the second user is watching and providing support.

This has the disadvantage that control of the host computer must be given to the remote user. There may be security issues with this that may prevent it from being allowed due to corporate policies. There may also be firewall implications with desktop sharing.

A further disadvantage from a learning perspective is that the user sharing their screen gives up control and they will not be the one driving their application by typing and making the required inputs.

The user who gives control can no longer operate their computer. If, for example, a chat message appears that they need to respond to, then they must take back control, attend to with the chat message answer, and then give up control again.

Remote control can also only be given to one user at a time. In a scenario where multiple users are on a conference providing assistance, each has to be given control one at a time making the interaction disjointed and involving a lot of latency during control switching.

Another option is to use a web conference to display the display of the whole screen or a selected application displayed at the host computer system to multiple remote computer systems. A user observing the display provides help and assistance through verbal or typed instructions.

In one example, a web conference may take place at the same time as a phone call so the user providing assistance might say, “type xxxx into the volume serial text box and press next”. The disadvantage of this is that support may be provided across languages so that there may be a translation issue with verbal instructions. Also, delays in the display being relayed to the remote observer may cause confusion.

One or more users providing support might also type their instructions into a text area, such as a comments panel or chat area in a web conferencing application. For example “Type value xxx into control yyyyy”. The advantage this has over desktop sharing is that multiple users can interact and have a conversation about the way to provide assistance.

This has the disadvantage in that it is in a separate area of the screen and it requires the user displaying their application to read this, translate it back to the action they need to perform and is therefore error prone and includes latency. In some cases, if there are multiple buttons or controls with the same label then it is difficult to identify the control being referred to in the screen being displayed.

With web conferences that include latency it is also possible that an instruction such as “type next on the wizard” is typed for one wizard page, but the user has advanced to the next page when they receive it and type. There is a need to tie the instruction to the control.

SUMMARY

According to an aspect of the present invention there is provided a computer-implemented method for providing instructions during remote viewing of a user interface, the method carried out at a host computer system and comprising: capturing an image of one or more application user interfaces as displayed at the host computer system; serializing data of each application user interface to provide a map of each window class and containers and/or control elements of the window class, wherein a container has attributes and child control elements; transmitting the captured image and the map to a remote computer system; and receiving control element input instruction from a remote computer system for instructing an interaction with a control element for display in a context of the control element in the application user interface.

The method has the advantage that an image of the one or more application user interfaces together with the serialized data map provides an exact reference of a control element enabling a remote user to provide an input instruction in context. The received input instruction may be displayed in the context of the control element at the host computer system.

Serializing data of each application user interface may include analyzing each window class in an active application user interface to identify the containers and/or control elements provided by the window class. Providing a map may include a type, size and location of each window class and a type, size and location of each container and/or control element within a window class. Serializing data of each application user interface may analyze each level of window classes from the top-most level downwards in the display and may record the level in the map.

The method may include enabling the control element input instruction to be activated in or entered into the application user interface further to confirmation input from a user of the application user interface. This has the advantage that the host computer system user may accept the input instruction without having to copy and past any text or interact with the control element itself. Displaying the input instruction in a context of the control element in the application user interface may include displaying the control element input instruction adjacent or referencing graphically the control element.

Receiving a control element input instruction may include one or more of the group of: a control element type, a control element location, a control element identifier, and a remote user identifier. Receiving a control element input instruction from a remote computer system may be received with a returned original image and/or map to verify that the application user interface is still current and the instruction is applicable to the application user interface.

The method may include receiving a holding indication that a control element input instruction from a remote computer system is currently being input at the remote computer system.

According to another aspect of the present invention there is provided a computer-implemented method for providing instructions during remote viewing of a user interface, the method carried out at an instructor computer system and comprising: receiving an image of one or more application user interfaces as displayed at a host computer system and a map serializing the data of each application user interface including each window class and containers and/or control elements of the window class, wherein a container has attributes and child control elements; identifying a control element in the map by reference to the image; receiving input of a control element input instruction from a user of the instructor computer system; and transmitting the control element input instruction to the host computer system.

Identifying a control element may includes: selecting a point or area as a location in a received image; and referencing the map to identify the control element at the location. The map may include multiple levels of window classes and identifying a control element in the map by reference to the image may include hit testing each level of window class.

Receiving a control element input instruction may include: displaying an instruction template for the type of control element identified; receiving the input instructing in the instruction template; and creating a control element input instruction.

Transmitting the control element input instruction to the host computer system may include transmitting one or more of the group of: a control element type, a control element location, a control element identifier, and a remote user identifier. Transmitting the control element input instruction may transmit a returned original image and/or map to verify that the application user interface at the host computer system is still current.

The method may include transmitting a holding indication to the host computer system and any other remote computer systems that a control element input instruction is currently being input at the remote computer system.

DETAILED DESCRIPTION

The described method and system enables user of a host computer system to receive instructions from user of a remote computer system relating to interaction with control elements on the host computer system display. The instructions are tailored to the actual display contents of the host computer system and provided in the context of the display contents without the need to provide control to the remote user of the host computer system.

The method and system at the host computer system send an image of the display to one or more remote computer systems along with serialized data relating to location, size and type of control elements or widgets of the display. The entire screen or only certain applications or windows displayed on the screen may be captured in this way.

A remote user may selecting an area of the display and may sending instructions to the user of the host computer system in relation to a particular control element in the selected area of the display. When remote users click on an area of the image, the control element is identified accurately. The inputs from the remote users are then sent back to the host machine.

The host computer system may display the instruction next to or with a pointer to the control element. The host user may select the instructions being displayed such that the data from the instructions may be entered into corresponding field of the control element. Multiple remote users may provide instructions simultaneously to a host user. In this way the host user interacts with their computer under the instruction of one or more remote user.

Referring to FIG. 1, a block diagram shows an example system 100 in which the described system and method may be implemented. A host computer system 110 may include at least one processor 111, a hardware module, or a circuit for executing the functions of the described components which may be software units executing on the at least one processor. Memory 112 may be configured to provide computer instructions 113 to the at least one processor 111 to carry out the functionality of the components.

The host computer system 110 may include a display component 120 for providing one or more application user interfaces 130. The application user interfaces 130 may include an operating user interface, installed application user interfaces, web services user interfaces, or other program user interfaces. The application user interfaces 130 may be graphical user interfaces, web user interfaces, command line interfaces, etc. The host computer system 110 may be a personal computer, a server, a handheld computing device, or any other form of computer system that may display user interfaces.

An application user interface 130 may include one or more windows 131, each having multiple control elements 134, 136. The control elements 134, 136 may be contained in containers 132. A window 131 may include a hierarchy of containers 132 and control elements 134, 136.

A window is an area of the display with its contents displayed independently from the rest of the screen and consisting of a visual area containing some of the graphical user interface elements of the program it belongs to. A window may be placed in front of or behind another window in the display.

A control element (also referred to as a control or widget) is a graphical user interface element of interaction. Control elements are software components that a computer uses to interact with an application. Each control element may enable a type of user-computer interaction and appears as a visible part of an application user interface. A container may be a form of control element that includes a group of other control elements, for example, a container may be a window or panel providing multiple options. Examples of control elements include buttons, scroll bars, text boxes, labels, check boxes, etc.

The described system provides a host instruction component 140 at the host computer system 110. The host instruction component 140 includes a transmitting component 141 for transmitting an image 151 of the one or more application user interfaces 130 displayed at the display component 120 of the host computer system 110. The transmitting component 141 also transmits a map 155 of the serialized data of the location and size of the containers 132 and control elements 134, 136 in each application user interface 130. Further details of these aspects are given below. In this way, the host instruction component 140 transmits details of the application user interfaces 130 on display to one or more remote instructor computer systems 160.

Multiple instructor computer systems 160 may be in communication with the host computer system 110 via a network 105 and may receive information from the host computer system 110 in order to enable them to provide instructions to the host computer system 110 relating to application user interfaces 130 displayed at the host computer system 110. An instructor computer system 160 may include at least one processor 161, a hardware module, or a circuit for executing the functions of the described components which may be software units executing on the at least one processor. Memory 162 may be configured to provide computer instructions 163 to the at least one processor 161 to carry out the functionality of the components.

The host computer system 110 may include the functionality of an instructor computer system 160 and visa versa so that a computer system may operate as a host or instructor as required in a given situation.

An instructor computer system 160 may include an instruction providing component 180 including a receiving component 181 for receiving the image 151 and the map 155 of the application user interfaces 130 as transmitted by the host instruction component 140. The instructor computer system 160 may include a display component 170 for displaying the received image 151 including images of the windows 152, containers 153 and control elements 154, 157 of the application user interfaces 130. The instruction providing component 180 may include an input component 183 for receiving and processing an instruction 156 input by a user of the instructor computer system 160 in relation to a control element image 155. The instruction providing component 180 may include a transmitting component 182 for transmitting the instruction 156 to the receiving component 142 of the host instruction component 140 of the host computer system 110. Further details of these components are described below.

In one embodiment, the application user interfaces 130 of the host computer system 110 may be displayed at the instructor computer systems 160 using a display component 170 of a web conferencing system and the web conferencing system may display the received image 151 and enable instruction input as described herein.

Referring to FIG. 2A, a flow diagram 200 shows an example embodiment of an aspect of the described method for providing instructions during remote viewing of a user interface. The method is carried out at a host computer system 110 that receives the instructions from one or more remote instructor computer systems 160.

The method may capture 201 an image of one or more application user interfaces displayed by the host computer system 110. Capturing 201 an image may use a screenshot to create a digital image of what is visible on the display component 120. This may an image of one or more application user interfaces 130 or an entire screen.

The method may serialize 202 the data of the each application user interface captured in the image to provide a map of window classes and their containers and control elements. A serializer component may walk the active display of each application user interface. From the active display, the top level components will be window classes with size and location. Each window class may then be analyzed for its children, which may be control elements or containers. A container has children control elements and can also have attributes such as the title (for example, if it is a group box), or items (for example, if it is a tree, table or list). Control elements and containers have size and location; the location may be provided relative to the parent container. The map may also include types and identifiers of the control elements.

Serializing may use calls to the windowing operating system. The ability to determine the graph of a window and its children is available in operating systems. For example, Microsoft Foundation Class Library (MFC) for Windows operating systems (Windows is a trademark of Microsoft Corporation), Carbon application programming interface for Mac operating systems (Carbon and Mac are trademarks of Apple Inc.), and Linux operating systems through GTX (Linux is a trademark of Linus Torvalds).

The captured image and the map may be transmitted 203 to one or more remote instructor computer systems 160. In one embodiment, this may be incorporated into a web conferencing system.

The display of the host computer system 110 may be monitored 204 to determine if this changes. When the display changes, a new image may be captured 201 and a new map serialized 202. The new set may be transmitted 203 to the remote instructor computer systems.

The host computer system 110 may receive 205 control element input instructions from any of the remote instructor computer system 160 for instructing interaction with a control element of an application user interface.

The host computer system 110 may check 206 that the display has not changed and the captured image and map to which the input instruction relates is still current at the host computer system 110. In one embodiment, this may be checked by receiving from the instructor computer system 160 the instruction input together with the returned original map as received at the instructor computer system 160 and used to generate the instruction input. In another embodiment, the captured image may be returned to the host computer system 110 for verification.

The map or image or both may be used to compare whether the display at the host computer system 110 is the one as displayed at the instructor computer system 160. If the display matches, the instructions are then used to identify 207 the control element on the host computer system 110 by matching the location and control element identifier. This may be by referencing the control elements in the map. Identification of the control may be based on an identifier in the input instruction. The identifier may include one or more of: the type of control element, the location in the map, a control element identifier, and any label of the control element.

The control element input instructions may be displayed 208 referencing the control element in the application user interface in the context of the control element. The referencing may be by displaying 208 the control element input instructions adjacent the control element, for example in a pop-up window on the application user interface that shows the input instruction alongside the control element, or by an arrow pointing to the control element.

The method may enable 209 the user of the host computer system to activate or insert the control element input instruction into the control element of the application user interface, for example, by selecting a provided acceptance control element.

In one embodiment, the host computer system 110 may create a widget such as a pop-up window adjacent to the control element. The pop-up window may include the input instruction (for example, text to input or the option to select) and an acceptance input (for example, an “OK” button). The pop-up window may also identify the remote user who provided the input instruction. The input instruction may be able to be accepted directly into the control element by using the acceptance input. In some embodiments, multiple instructions against one control element may be received from multiple remote users. These instructions may be displayed in multiple pop-up windows with one for each remote user.

Referring to FIG. 2B, a flow diagram 250 shows an example embodiment of an aspect of the described method for providing instructions during remote viewing of a user interface. The method is carried out at an instructor computer system 160 that provides instructions to a host computer systems 110.

The method may receive 251 an image of one or more application user interfaces, which may be displayed 252 at the instructor computer system 160. The received image shows the one or more user interfaces or the entire screen as displayed at the host computer system 110. Serialized data may be received 253 for each application user interface as a map of the window classes and their containers and control elements.

In one embodiment, the application user interfaces 130 of the host computer system 110 may be displayed at the instructor computer systems 160 using a display component 170 of a web conferencing system and the web conferencing system may display the received image instead of a web conference feed in the display component 170.

An input by a user at the instructor computer system may be received 254 as a selection of a point or an area of the displayed image relating to a control element the user wishes to provide an instruction for. The method may identify 255 the control element by referencing the location on the displayed image and the map of the serialized data.

The type of control element may also be identified and an appropriate instruction template presented 256 to the user for the type of control element. A control element input instruction may be received 257 from the user input into the instruction template.

A user of the remote instructor computer systems is able to select an area of the display and the instruction providing component may look at the map of the display control elements to determine which the control element lies beneath the cursor. If it is a text area, then the user may be given the option of providing instructions for a text box such as “type ______” or “Press ______ key”. If the control element is a button, the user may be able to give instructions relevant for a button such as “press Enter”.

The control element input instruction may be transmitted 258 to the host computer system with an identifier of the control element. For example, details of the location and control element type may be provided. The input instruction may include the text input or the option specified by the remote user depending on the type of the control. The instruction may also include the remote user identifier so that the user of the host computer system knows who has made the input instruction suggestion. The location and the type of the control element may be used to match a control element at the host computer system by referencing the map that was generated and sent to the instructor computer system.

A return map and/or a copy of the image may be returned 259 to the host computer system with the input instruction in order to verify that the same content is still being displayed by the host computer system and therefore the instruction input is valid for the display.

For the user of the host computer system, when they receive the instructions, rather than the instruction just being shown in a separate chat area, the instruction appears in the context of the control element. The user can see what control assistance is being provided for, and they can also accept the instruction resulting in the text being entered, the button being pressed, etc.

In one embodiment, an instructing user of a remote instructor computer system may provide input instructions for all the control elements of a container in a single instruction.

In one embodiment, the host computer system may serialize the data of the application user interfaces into Extensible Markup Language (XML) with the control type, size and location.

An example of the serialized data for an application user interface 130 of a wizard page such as the one being displayed in FIG. 4B would be:

<Window location=10,10 size=70,130>  <Container location=0,0 size=70,20> ....... (The controls for title bar of the wizard) .....  </Container>  <Container location=0,20 size=70,80>   <Label location=5,5 size=20,10 text=“Volume serial:”/>   <Text location=30,5 size=30,10/>   <Text location=5,22 size=20,10 text=Generic unit”/>   <Text location=30,22 size=30,10/> ............  </Container>  <Container location=0,80 size=100,20>   <Button location=15,3 size=20,7 label=“Back”/>   <Button location=40,3 size=20,7 label=“Next”/>   <Button location=55,3 size=20,7 label=“Cancel”/>   <Button location=70,3 size=20,7 label=“Finish”/>  </Container> </Window>

A single application at the host computer system 110 may be captured and sent to the remote instructor computer systems. Optionally, several applications may be selected to be captured and sent. In one embodiment, an entire display at the host computer system 110 may be captured and sent to the remote instructor computer systems.

If multiple application user interfaces or an entire display is being captured, then the serialized data for every application user interface is created and sent to the instructor computer systems. For each active window the z order is included in the serialized data. The z order is the order that the windows are placed on top of each other, so that an application that is in front of everything has a z order of zero, the application behind that has a z order of 1. This is so that the mapping between locations and control elements does not give a false positive if a control element is behind another. For any window it is possible to work out whether it is being masked or obscured by another by asking for the bounds of the paint area.

Referring to FIG. 3A, a flow diagram 300 shows an example embodiment of an aspect of the described method for providing instructions as carried out at a host computer system 110 for multiple application user interface windows or an entire display at the host computer system 110.

The serializer component may walk 301 the active display. The active display may be the application user interfaces selected to share with the remote instructor system. The user at the host computer system may choose to share one or more application user interfaces or to share the entire screen.

Windows may be positioned on top of each other and the top-most window may obscure windows that are beneath it. Window order is known as a z order (with x and y being left to right and top to bottom axis) and z being out of the screen.

A top-most window class is selected 302 and added to the map with its size and location. The window class may be analyzed 303 including traversing containers and control elements within the window. The containers and control element with their type, size and location are added 304 to the map.

It may be determined 305 if there is a next level of window class in the active display. If so, the method goes to the next level down 306 in the display and the method may be repeated to build 302, 303, 304 the map.

If it is determined 305 that there is not next level of window class, the map may be transmitted 307 for the active display.

Referring to FIG. 3B, a flow diagram 350 shows an example embodiment of an aspect of the described method for providing instructions as carried out at an instructor computer system 160 for multiple application user interface windows or an entire display at the host computer system 110.

The method may receive 351 a user selection of a point or an area in the displayed captured image and may reference the serialized data map in order to identify a control element at the point or in the area.

The method may look up the visible window in the selected area of the first level of the map using hit testing. The first level will be a level with a z order of zero.

The technique of “hit testing” is where each window is asked whether the coordinates (x,y) of the cursor are contained within its currently painted area by comparing the window's location and size with the location of the cursor to see whether it lies within its visible painted bounding box. The order that windows are asked is in z order with the outer-most “on top” window asked first, followed by the windows beneath it. The first window that contains the cursor coordinates, x and y, within its bounding box will be the window that is visible to the user.

It may be determined 353 if the hit test is successful in the window level. If it is not successful, the method progresses to check the next level down 354.

If the hit test is successful for a window, then the children in the target window are checked 355 and the window's containers and control elements are asked whether they contain the cursor. Only one control element may give a positive hit result at any given level for whether the cursor is contained within its bounds as the tree of containers and controls are traversed recursively. This is done in reverse z order so controls on top are asked before controls that they obscure. The first control that is found that contains the cursor x and y location in its rectangle is the one beneath the cursor. This is known as hit testing.

The result of the hit test is that one, or none, control elements will answer that they are the one that the cursor has been pointed at.

In this way the method may obtain 355 the result of the control element in the selected area that is hit and may determine the type of the control by looking up the control element in the map.

An instruction template for the type of control may be presented 357 to the user and user input may be received 358 in the instruction template. The instruction input may be transmitted 359 with the control element location and identifier to the host computer system.

When the instructor finishes his/her input by pressing ‘Enter’, the following example XML is constructed to indicate the input instruction from this user.

    <Window location=10,10 size=70,130 instructor=     “John Smith” >  <Container location=0,20 size=70,80>   <Label location=5,5 size=20,10 text=″Volume serial:″/>   <Text location=30,5 size=30,10 input=″201610280005″/>  </Container>  <Container location=0,80 size=100,20>   <Button location=70,3 size=20,7 label=″Finish″ clicked=″yes″/>  </Container> </Window>

In this example, two control elements are identified, a text input and a “Finish” button. Each control element is identified by its container location, control element location, and label name. The instructing user is also identified.

In another example XML a control element identifier may be generated and included in the XML.

Referring to FIGS. 4A and 4B, an example application user interface 130 is shown. FIG. 4A shows the image 151 of the application user interface as presented at an instructor computer system and FIG. 4B shows the application user interface 130 at the host computer system. The application user interface 130 has a menu panel 410 in which an option 411 has been selected resulting in a window for a container 132 being displayed. The container 132 includes labels with associated text boxes 421, 422 and a label with a drop down menu 423. Buttons 424-427 are provided for back, next, cancel and finish operations.

FIG. 4A shows that, a control element 421 in the image 151 of the application user interface is selected by the instructing user by pointing a cursor 430 at the control element 421. An instruction template 431 for the type of control element is displayed with a set of options for instructions for how to use the keyboard or mouse, for example, a text area has the instruction “Enter text: . . . ” or “Type . . . ”. In this case, the instructing user has an area to type the text they wish to be entered into the text box. The instructing user can then type the value, for example “201610281005” in a text area on their screen and press “Enter” to signal they have finished.

If the control element beneath the cursor 430 were a button, then the user would get a different set of actions, such as “Click” or “Double Click”. If the control element beneath the cursor were a scroll bar then the user would get a different set of actions such as where the scroll bar should be moved to. The set of actions is determined by knowing the control element type.

As shown in FIG. 4B, for the host user who is displaying their application at the host computer system, when the host instruction component receives the input instructions these contain, not only the text, but the control location they are relevant to as well as the control element identifier. This is used to locate the control and open a pop-up 441 that shows the instructions alongside the control element 421 in the application user interface 130. Depending on the control element, these may be able to be applied directly (such as typing into a text field, or pressing a button) in which case an “OK” button 444 may be provided allowing the host user of the application to just accept and apply the instructions from the instructing user who provided the assistance.

In the example shown in FIG. 4B, an instructing user “John Smith” is identified 442 as providing the instruction and the text value 443 of “201610281005” is provided in the instruction. The host user can see which control element 421 it is for with a visual indication 440 (such as an arrow) and they can press the “OK” button 444 to accept and have the value entered into their text field in their application user interface 130.

There may be multiple instructing users with instructor computer systems on which the application user interface 130 may be viewed using the described system. When one of the instructor starts to provide an instruction by making an input at their instructor computer system, other instructing users and the host user may receive notification that one of the observers is typing with the name and an indicator that an action is pending, such as “ . . . ” against the control element. For example, “John Smith . . . ” in this example.

When one of the instructors points the cursor in an area, which is detected by his/her instructor computer system, the system creates and sends the following example XML to the host computer system along with the original image. The host computer system determines that the current display matches the original image and then broadcasts the XML to other computers.

    <Window location=10,10 size=70,130 instructor=     “John Smith” >  <Container location=0,20 size=70,80>   <Label location=5,5 size=20,10 text=″Volume serial:″/>   <Text location=30,5 size=30,10 pendingforinput=″yes″/>  </Container> </Window>

When the instructing user has finished typing all the users may see the instruction and they are also able to add or comment in the same way. So that in the case of a multi-user conference, the host user displaying their screen may get collaborative input from everyone as to the correct action to take. This can be useful in an environment where more than one user is helping the primary user sharing their screen with a problem or issue they need assistance on how to drive their application user interface.

When the instructing user sends their instruction back to the host user, they also send back the map and image that was shared with them. This is compared against the host user's application user interfaces. If the host user is showing a different application, perhaps the next page of a wizard, then the instruction is not applicable and the user will not type or press a button against the wrong user interface element. As soon as a instructing user starts to provide an instruction, the host sharing will see the “ . . . ” to indicate that a user is suggesting their instruction. This allows the host user to wait until the instruction has been completed and sent, so the interaction model is one where the instructors can “pause” the host user, type an instruction, send the instruction, and have the application being displayed compared to that which the instruction was created, with accuracy reducing errors and increasing the skill and knowledge sharing between the host and the instructors.

Referring to FIG. 5A, a block diagram shows further components of an example embodiment of the host instruction component 140 of the host computer system 110 provided in association with a display component 120 as shown in FIG. 1.

In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

Cloud Computing

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 7, illustrative cloud computing environment 750 is depicted. As shown, cloud computing environment 750 includes one or more cloud computing nodes 710 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 754A, desktop computer 754B, laptop computer 754C, and/or automobile computer system 754N may communicate. Nodes 710 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 750 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 754A-N shown in FIG. 7 are intended to be illustrative only and that computing nodes 710 and cloud computing environment 750 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 8, a set of functional abstraction layers provided by cloud computing environment 750 (FIG. 7) is shown.
